A very complex machine utilizing a combination of torsional motion and varying stresses and strains, implemented by a complex system of pulleys and hydraulic levers. The system, operating at an astronomical 72% efficiency, is perfect for thermodynamic calculations, maximizing the output of the internal combustion engine, cooking eggs, and jerking off chodes.

Dude1) "Did you finish calibrating the hydrolic pressure meter on the jerkoff-mobile?"
